WINDMILL.

SPECIFICATION forming part of Letters Patent No. 334,813, dated January 26, 18. 6. Applicatitn filed June 6, 1884. Serial No. 134,027. (No model.)

To all whom it may concern.-

Be it known that I, ALVIN SHERWOOD, a citizen of the United States, residing at Hampden township, in the county of Coffey and State of Kansas, have invented certain new and useful Improvements in \Vindmills, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in windmills, and is designed to produce a mill which is easily and readily constructed, and at comparative little expense,and simple in operation, and still be' employed for pumping or running machinery at a considerable distance.

The improvement consists in the mechanisms employed in the manner claimed.

In describing the device reference is had to the annexed drawings, in which Figure 1 represents a side elevation of the device; Fig. 2, a plan or front view of the wheel carrying the wings; Fig. 3, a detail view of the pitman; and Fig. 4 is a view of the controlling-wing and its retainingspring.

A suitable standard, A, is provided, being, though not confined to, a single upright, as shown. On this standard is raised a short cylindrical post, B, pivotally supporting the crane C. By means of suitable bearings this crane carries a lateral shaft, E, having at its outer end two or more arms, E, at right angles to said shaft. The wings H are pivoted or hinged centrally to the arms E by means of rods 1, (one or more,) ending in a crank,I. The cranks I engage in a connecting rod or arm, K, on the sleeve M. At the other side of the pivotal point to that on which is the wheel is raised a standard, T, on the crane, forming a pivotal support for a lever consisting of the long arm U, the short arm Y, and the arms U and T, projecting, respectively, on opposite sides of the pivotal point and relatively at about right angles to the arms U and Y. The arms Y and U are connected by a curved arm, Y. The arm U projects above the arm Y, and at its end carries, pivotally, the wing R, kept normally in an upright position by the spring W'. The arm T has connection with the sleeve M by means of a rod, S, and is also connected to a short projecting arm of an angle-lever consisting of the arms W and B", pivoted at the angle to the end of the arm D of the crane C.

To one arm of a cross or X lever, F, which is pivoted in suitable bearings, F on the standard A, is secured a sleeve, G the upper end of which is swiveled to a pitman-rod, as shown at G. This rod ends in a head, F, having a lateral slot, as shown in Fig. 3, in

which plays a wrist-pin on a small pulley or wheel, B, on one end of the shaft E, by means of which a direct stroke is given to the said pitman. By means of a lever, H", similar to the lever F,and rods G connecting coinciding arms of the said levers, the power is transmitted, the space or distance through which it passes being determined by the length of the said rods G". The lever H" is mounted on suitable bearings and either carries on one of its arms a pawl-rod, G, actuating a ratchetwheel, A, on the shaft of which may be mounted a transmitting-pulley for imparting motion by means of a belt; or to either the lever F or the lever H may be connected the pump-rod. (Not shown.)

To the connecting-arm Y is secured a cord, X, secured to a rod, X, passing downward through the post B and sleeve G and pivoted to a lever, O, which has a downward extension, D, forming a bearing for the float D The rod X is provided with a :swivel, A, which permits the upper portion of the said rod to turn with the wheel and crank as they swing to the wind.

To the standard is secured a Windlass, C having a cord connecting to the rod X at or below the swivel.

The wings, which may be in number two or more, according to the work for which the mill may be constructed, are, when more than two, connected by rods N, and when a steadygoverned motion is desired are provided with weights P on the edge toward the pivotal point of the crane. The wind reaches the wheel from'the direction shown by the arrow, Fig. 1, the said'wheel operating in lieu of a tail to properly guide the mill and keep it in proper position to the wind, and the wings to be presented to the wind must carry the weights forward in the direction of the rotation. As the wheel increases in speed, the

weights will tend to carry them to a position at right angles to the plane of rotation, and thus present less surface to the wind.

reaches some specified speed.

The weight A, suspended by a cord or rope from the arms U and W" may be moved and secured on said rope so as to bear on one or the other of said arms. If it bears on the arm U, it tends to keep the wings at the proper angle for running the machine, and a greater speed of wind is necessary to operate the wing R, and the reverse is also true.

The wing R is made of considerable weight, so as to normally tend to keep the wings at the proper angle, the said wing being normally inclined toward the wind.

Either the float or Windlass will operate to move the wing R toward the wheel, and so stop the same, the first temporarily, the latter permanently, if so desired.

The pitman-head and crank-pin may be dispensed with and gearing substituted, if so desired.

I claim- 1. A windmill having a wheel with pivoted wings, a crane or pivoted frame supporting said wheel, a wind-wing pivoted to suitable bearings on the crane, a wind-wing also pivoted to the crane and projecting in a direction opposite to the other wing, and a weight supported by a cord or rope having connection to each wing, substantially as and for the purpose specified.

They. are so adjusted as to operate when the wheel 2. A windmill with a wheel having wings pivoted to the arms of the wheel by rods terminating in cranks, a sleeve on the wheelshaft connecting with said cranks, a crane or pivotal support for the wheel, a wind-wing pivotally supported by said crane and connected to the said sleeve, a wind-wing supported by the crane and projecting oppositely to the other wing and connected to the wings on the wheel, and a weight on a cord or rope which has connection to the wings, substantially as and for the purpose specified.

3. A windmill consisting of a standard, a crane mounted thereon, a wheel having bearings on the crane, wings pivoted to the arms of the wheel by rods having crank-continua tions, a sleeve on the wheel-shaft engaging with said cranks, oppositely-projecting pivoted wind-wings, one of which is spring-retained, pivoted to the crane, a weight supported by a cord or rope connected to the wings, a pitman with a swiveljoint operated by the wheel-shaft, and a cord or rope connected to one of the wind-wings and passing down the standard, the whole operating substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
